GRAIN-CAR-DOOR CONSTRUCTION.

Specification of Letters Patent.

Patented Oct. 17, 1911.

/ Application filed November 12, 1910. Serial No. 592,046.

To all whom it may concern:

Be it known that I, HERBERT W. DREW, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Grain-Car-DoorConstruction, of which the following is a specification.

This invention relates to improvements in grain car door constructionand provides a construction whereby the door of a grain car may beeasily maintained in a closed position or allowed to open at the will ofthe operator.

Referring to the drawings Figure 1 is a side elevation of a grain carshowing the grain door in closed position. Fig. 2 is a transversesection along the line 2, 2 of Fig. 1. Fig. 8 is a partial sectionalview along the same line as Fig. 2 and showing the looking mechanism ina position preparatory to opening the door. Fig. 1 is a partial sectional view along the same line as Figs. 2 and 3 showing a part of thedoor in open position. Fig. 5 is a vertical sectional view through thecar door showing the mechanism in locked position. Fig. 6 is a verticalsectional view along-the same line as Fig. 5 showing the doorpreparatory to the opening of the same. Fig. 7 is a vertical sectionalview on the same line as Figs. 5 and 6 showing the door in an openposition. Fig. 8 is a perspective of the details of the operativemechanism. Fig. 9 is a perspective showing the mechanism in lockedposition. Fig. 10 is a perspective showing the mechanism in an openposition.

The grain door construction and general car construction is the same asthat shown and claimed in my prior application No. 54:7,107, filed March3, 1910.

The object of this invention is to provide in place of the operatingmechanism for the grain door shown in that application another means ofholding the grain door in locked closed position or to permit of .itsbeing easily opened.

The same numerals refer to the same elements throughout the drawings.

The numeral 10 designates a grain door having a handle 10 to enable itto be readily opened and closed, manually if desired.

11 designates a T-shaped member with a vertical flange 11. i

12 designates an angular member to which the grain door is secured oneither side. These angular members 12 have inwardly turned flanges 12 attheir bottom extremity, these flanges 12 being inwardly turned on thebottom edge of the grain door 10. The locking mechanism' 13 is composedof the two members 13, 13 pivoted tothe door at 13 and to the flange llat l3, respectively, and hinged to each other at 13. These members 13and 13 have apertures 13 referred to hereinafter. The numeral 14 is usedto designate the locking lever which is pivoted at one extremity to theside flange of the member 12 and carries at its other extremity a stud15. The angular member 12 is pivoted at 17 to the flange member 11 andis spaced therefrom by means of a collar 16. Near thelower extremity ofthe locking lever 1 1 the latter is bent inwardly then downwardly asindicated at 18 for a purpose hereinafter described.

The members 13 and 18 are made of equal length and their axes ofrotation 13* and 18 when the door is closed coincide so that when thedoor is in a closed position and the members 13, 13 lie together, as indicated in Fig. 9, for example, they may rotate about a single axis.

In the operation of this device when the door is closed and the twomembers 13 and 13 come into juxtaposition preparatory to*' ing of thegrain door 10. When it is desired to open the door the lever 14 isdisengaged from the members 13, 13 and the latter are rotated into theposition indicated by dotted lines in Fig. 6, whereupon the door willopen either by reason of the weight of the inclosed grain or by means ofa slight pull on the handle 10.

In reversing the operation when the door is open a slight tap at 13where the locking members are hinged will throw them out of dead centerand permit the door to be easily closed, whereupon it may be locked asshown in the drawings. This device furnishes a simple means of holdingthe door in locked "position and is easily operated. It is to be notedthat the collar 16 spaces the members 11 and 12 far enough apart toallow the looking members to lie in a closed position and out of the waybetween the flange 11 and the inwardly turned flange of the member 12.

By fitting the side of the door opening with the T-beams 11 I obviate avery common difliculty in this class of cars, namely, the necessity offrequent coopering, which is not only comparatively costly, butnecessitates the withdrawal of the car from active service. The T-beambeing fastened to the side of the car, as shown and described,reinforces the side boards at their weakest point anttalthough they maybulge and warp this construction insures an even contact between thedoor and the side flange of the Tmember and prevents the escape of grainas well as insuring the easy operation of the door by preventing anyjamming.

I claim:

1. In a car, a grain door, a flanged mem ber connected to one side ofsaid door, a T-member connected to said car adjacent to said door, apivotal connection between said first named member and said T-member,and a hinged locking device connected to each of said members wherebywhen said locking device is in one position said door is locked and whensaid locking device is in another position said door may be opened.

2.
